Java Servlets you create that extend HttpServlet must be mapped in the web.xml like the following:- In this Test GAE project ecipse generated sample code that created a Java Servlet called TestServlet.class that extends HttpServlet and is appropriately mapped. To run your app you need to include the url mapped to the TestServlet.class found in the web.xml (In this case /test) in your index.html. (In the case of generated project sample code created by eclipse this will already have been done). Once your Java Servlets are correctly mapped in the web.xml and included in your index.html the mapped url that is clicked will invoke the appropriate Servl

app is over its bandwidth quota, respond with 503 Service Unavailable instead of 403 Forbidden 1 person starred this issue and may be notified of changes. Back to list Status: Acknowledged Owner: ---- Type-Feature Priority-Medium Component-Serving Sign in to add a comment Reported by alexkon, Nov 3, 2012 According to the docs, when an app has exhausted its bandwidth quota, App Engine returns a 403 Forbidden status code [1]. According to the Release Notes for version 1.2.8, it returns 503 Service Unavailable or maybe 500 Server Error [2]. The documentation is inconsistent and it's hard to test what is the behavior in production. This is a request 1) to fix the actual status code returned and 2) to make sure the docs are consistent with the actual behavior. When the bandwidth quota is over, please return the 503 Service Unavailable error. That is the most informative status code that the HTTP/1.1 spec defines for transient serving problems [3]: The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. Compare this to the definition of 403 Forbidden [4]: The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. The difference between the 4XX and the 5XX status codes amounts to the following. 4XX: The server is functioning properly. The problem lies with the request, be the URL or something else. Trying the same request again does not make much sense, because the request might ever succeed only if some semantic changes are made to the website, e.g. the missing page is created its permissions are changed manually. Trying another URL (e.g. the homepage) makes perfect sense, because the error is with the specific URL requested. 5XX: The server has experienced a problem; we don't know whether the URL and the request are good. If they have succeeded in the past, they probably are. Trying again later makes sense, because the problem might be fixed any time either without human intervention or by the people in charge of the site's reliability. Trying another URL (e.g. the homepage) might n
